I had my 165 in for 25hr service check and oil change today. Service manager Jeff at Dockside Marine in Willmington Il sounded very knowledgable of the Scarab rotax setup. I asked him how to get more mph , he said he would set me up with different pitch impeller and some other upgraded parts, relatively not too expensive and he would help me get as close to 60mph as possible without changing the ECU. I will wait on these mph enhancements options till maybe next summer. It's really cheek flapping fun At 50-54 mph on a 15' boat but only could imagine 60+. I seen some seadoo speedsters claim 60-65 mph on the 215-255 supercharged rotax , so why can't we fly like that ????

Let me know when you do this, I am very interested! As long as it doesn't interfere with getting out of the hole

Got my 165 back from the 1st oil change and was stuck at 36 mph but the water was choppy. Before the 1st oil change, I could get 38.5. My goal is 45 mph.
